[AK7722] AK7722 24bit 4ch ADC + 24bit 4ch DAC with Audio DSP GENERAL DESCRIPTION The AK7722 is a digital signal processor with an integrated 4ch 24bit DAC, a stereo ADC with input selector and a 2ch input ADC. The integrated 4ch DAC, the 2ch ADC with input selector and the other 2ch ADC feature high performance achieving 108dB, 96dB and 95dB, respectively. The integrated SRC has three input selector enabling the DSP to operate in master mode with digital inputs. The audio DSP has 1536step/fs (at 48kHz sampling) parallel arithmetic operation performance and the 5k-word delay RAM allows surround processing and time alignment adjusting. As the AK7722 is a RAM based DSP, it is programmable for various user requirements. It is housed in an 80pin LQFP package.
